Y 4 LD'MALCOLM'DUNCAN, a citizenof the United :States of America, temporarily residing at London, county of London, England, 'C ARLES H N YPBICHABD, of London, county of Lonv don, England, and CHARLES RIDGEWAY MACAULEY, of

. the'King of Great Britain, .have invented certain new cleanfand exact description of the same, reference'beinghad to th London, county 'of London, England, both'subjects of and usefullmprovements in Type Gasting Machines; and we do herebydeclare the following to be afull,

accompanying drawings, forming "a part (ii-this specification, and to the figures and letters of lrelerence marked thereon.

f Thisinvention lates to the class of. automatictype icasting and composing machines wherein individual types are cast in the order of composition and assembled in the form of lines in a galley.

Heretofore in machines of this class the quads have beenformed of' the same body lengtlias the character typ'e, consequently, when set or assembled for printing 7 or stereotyping, a very slight-elevation of the quads will bring their end's or faces'nearly .or quite into the flplane of the printing faces, thus causing an impression to'be madewherel'none is desired, and the object of the present inventioniis to remedy this inconvenience by the provision. of means whereby the quads may or shall be cast bodies considerably shorter than those oi the character'type.

To this enditheinvention consists in providing the mold with a cut-offladaptedto enter themold cavity and close the samezatfa point within and at a distance from that end of the mold cavity with which the matrices engage informing character type, whereby is an end view,

the bodies of type Q 1 ag i st said cutoff will be' shorter-than those lcast against matrices overlying the --enzl oithe typecavity'.

' The inventionralu consistsin the employment of a sectional mold-blade or mold adjusting member and one section thereof as the cut-off for closing ithe end of the mold, and in mechanism whereby the insertion arid withdrawal of said cut-off can be auto matically controlled and effected.

Fig. 6 is a top plan and 2 a top plan view of the mold tering pin lever with connections for automatically con trolling the mold-.blade sections and Fig. it is a side ele- 'vation of the same.

Similar numerals in the several figures indicate the same parts.

The type casting and composing machine with which the improvements are shown associated is that of Patent No. 625,998, of which only such parts are illustrated as are necessaryto a full understanding of theinvention; These include 'a portion of the main frame 1; the slide 2 by which the mold-blade is reciprocated; the adjustable abutment 3 for determining the position of the mold-blade; the side blocks 4 of the mold; the-cross blade 5 the main actuating lever 6 for the centering pin (not shown) and trip rods 7 of the justification adjnsting mechanism; and one of the main-shafts 8. The adjiistable mold-blade employed for varying thc'width of the mold cavity, instead of being made in one piece, as heretofore isdivided longitudinally into two sections 10 and 11, guided one upon the other in a manner to prevent lateral displacement and permit longitudinal; movement. The proximate faces of the two sections, are notched for the reception of the front stop or gage as shown in Fig, 3. When character type are to be cast the two sections 10 and 11 stand with their front faces in the 8 0 sanie plane, as indicated in Fig. 3, but when quads are to be formed the upper section 10 is advanced so as to project beyond the lower and engage the opposite wall of the mold cavity when the lower section 11 is in adjusted position, as seen in Fig. 4, thereby cutting ofi the upper section of the mold cavity, the under surface of the projecting section in lieu of the usual matrix, forming the end of the mold cavity. The cross pin 12 through which motion is transmitted from slide 2.1;0 the mold-blade, in dimensioning the mold,

is utilized for effecting this shifting of the sections oneupon the other, to which end said cross-pin is rendered movable in its bearings and caused to/act upon the'upper section 10, to advance and retract it as desired. In the present embodiment the cross-pin 12 '95 is longitudinally movable and is formed in cross-section with a straight section 13 riding ina slot 14 in the lower mold-blade section 11, and a flanged or card section 15 riding in a slot 16 in the upper section 10; The cam section 15 is furnished with beveled projections 17 on opposite sides and located at different points in its length, so that when the cross-pin is in one position it wi1l,'through the engagement of the bevel on shoulder 17 with the front wall of slot 16 cause the advance of the upper section beyond the lower section, and when the cross-pin is retracted. it will draw the upper section back andhold it flush with the lower section. The shifting of the upper upon the lower mold blade section, in either direction,

is effected through the medium of the intermediate portion of the cam formed by the two inclined or wedge surfaces extending from the apex of each shoulder or projection 17 to the rear face of the other, and when the cam is shifted so as to bring the rearward projection or shoulder within the slot 16 of the upper moldblade section the latter is locked and held against motion upon the lower mold-blade section by the engagement of the cam with opposite walls'of the slot 16. This portion or section of the cam thus performs the function of a latch or bolt carried by the cross-pin fitted to a groove in the lower mold-blade section and serving, when engaged, to loci; the two mold-blade sections together, for simuhtaueous adjustment, and

when withdrawn, to release the upper mold-blade section so that it will be freeto respond to the action of the shifting or inclined section of the cam. The front projection 01' shoulder 17 of the camully enters 2 the slot 16 in the upper section of the mold-blade only when the lower section is adjusted to form the rnaximum size type'body, the front incline operatingat other times to advance and hold the upper mold blade section beyond the end of the lower and in contact with the opposite wall of the mold. The shifting of the cross-pin when it is desired to produce a short bodied type may be variously cffectedand controlled, but in the present instance means are shown for automatically controlling the shift through the agency of the die-case movement, as will presently appear.

To one end of the cross-pin is attached a spring or compression devices, comprising, in the present instance, a box or casing 18 inclosing spring 19, and a bolt 20 secured to the head of the cross-pin. The

spring 19 is interposed between the end of casing 18 and head of bolt 20 and the inner end of the casing contacts with the head of cross-pin 12 so that when said casing is reciprocated it will operate positively upon the cross-pin in one direction to retract mold blade section 10 and elastically in the other direction, to advance said section. The casing 18 is furnished with a transverse slot or way 21 for the reception of a pin 22 carried by a lever 23 pivotally supported, as at 24-, upon the main frame and connected through lever 25 and rod 26 to a lever 27 working upon cam 28 on the'main shaft 8. An adjustable stop 29 may be provided to limit the throw of lever 23, the spring of the connections or of a spring box included in the transmitting devices permitting this adjustment. The

cam 28 is so shaped and positioned relatively to the rest ofthe machine that it will operate to shift lever 23 in a direction to cause the compression of spring 19 and a consequent shifting of the cross pin in a direction to advance mold-blade section 10 upon the lower section, just after the cross pin 12 has been moved laterally to press the lower mold blade section against the adjustable abutment to gage the .mold and the diecase has been moved to position to bring the selected matrix over the mold-cavity, thereby holding said section under elastic pressure against .the opposite wall of the mold cavity. In the absence of additional controlling elements this would result in a cutting out of the upper section of the mold cavity and prevent a cast being made against the selected matrix at the end thereof. In other words the mechanism just denated. It is obvious that these conditions might be reversed, that is to say, the action of the shifting dc vices be suspended for character type and permitted for quads, but the present arrangement is preferred. For normally locking out or suspending the action of the shifting devices described and for designating the times of action, to accord with the production of quads, the following mechanism has been devised;

When in normal position the, cross pin occupies its advanced position with the rear shoulder 17 in engagement with the upper section 10 of the mold-blade-and locking the two sections together at which time the faces of the two sections are in the same plane and the mold cavity is open. To retain the cross-pin in this position, as against the pressure of spring 19, whenacted upon by lever 23, the head of said cross-pin is furnished with a collar or shoulder 30 and the latter is engaged by an off-set 31 carried by a stiff spring 32 mounted upon and secured to the frame. This off-set 31 stands normally in rear of collar 30, and prevents retraction of the cross-pin, the spring 19 yielding under the action of lever 23 and assisting in holding andthereby positioning the cross-pin, the offset 31 constituting an abutment or gage for determining the normal position of the crosspin and through it the relative positions of the two mold-blade sections. I

Pivotally supported upon the frame is a lever 33 one end of which engages spring 32 and the other is engaged by a lever 34. Pivotally supported upon lever 34 is a trip rod 35 provided with adjustable nuts 36 and adapt,- ed to be swung into and out of engagement with a plate 37 attached to the main lever 6. A spring 38 connected to trip rod 35 serves to hold the latter normally in tilted I position with its upper end free from engagement with plate 37, but when said trip rod is tilted into the path of plate 37 and the latter is depressed (which action takes place after the selected matrix has been brought to position and before the cast is made) said trip-rod will be engaged and carried down, thereby tilting levers 3-1- and 33, and depressing spring 32 until off-set 31 is wi thdrawn from engagement with the cross-pin so that the latter is free to reciprocate-under the action of lever 23 and spring 19 thereby first unlocking the mold blade sections by withdrawing the locking section of the cam and then engaging the shifting section of the cam to advance the upper section 10 of the mold blade the lower section being previously or simultaneously adjusted to size the mold for the body width desired. After the cast has been made and before the ascent of lever 6 the return motion of lever 23 restores the crossvpin to normal position so that upon the release of the trip-rod off-set 31 will rengage the cross-pin and lock the latter in position until the trip rod is again tilted as they have position in the die-case the trip lever 35 will be engaged and the cross-pin subjected. to the control of its actuating mechanism.
